What is Duck.ai?
Duck.ai is a chat feature from DuckDuckGo that lets people talk to AI models made by other companies while DuckDuckGo anonymizes the exchange. The help pages name Claude Haiku from Anthropic, Mistral Small, two small GPT models from OpenAI and two open models hosted by Tinfoil.sh as free options, and say that DuckDuckGo subscribers on Plus or Pro plans get further advanced models. No account is required. Besides typed questions, the interface offers voice chat, image creation and editing, and uploads of photos and PDF files. Earlier conversations are kept in a Recent Chats list that is stored on the device itself; entries can be removed one at a time or all together with the Fire Button, and up to five can be pinned.
